1 Claim.

This invention relates to smoking devices such as tobacco pipes, cigar and cigarette holders.

The object of this invention is to provide simple improved means that can readily be applied to existing pipes without requiring any change in the structure thereof, to prevent the direct or concentrated draft of the smoke into the smokers mouth, with an accompanying burning or biting which is extremely unpleasant and annoying.

The primary object of this invention is the provision of a device of the above mentioned character set forth, that is simple in construction and inexpensive to manufacture, and extremely efficient in use and service.

In describing the invention in detail, reference will be had to the accompanying drawing, wherein like characters denote like and corresponding parts throughout the several views and in which:

Fig. 1 is a perspective view of a pipe in which the invention is applied,

Fig. 2 is a fragmentary enlarged vertical sectional view taken longitudinally through the mouthpiece,

Fig. 3 is an enlarged end elevational view of the same,

Fig. 4 is an enlarged side elevational view of the device,

Fig. 5 is an enlarged perspective View of another form of the device, and

Fig. 6 is a fragmentary enlarged vertical sectional view of another form of the device, taken longitudinally through the mouthpiece.

Referring to the drawing, a pipe is shown as comprising a bowl section I, which bowl section detachably carries a mouthpiece 2 in a manner well known in the art. The mouthpiece 2 is detachably connected at one end to the bowl section I and the free end is adapted for insertion in the smokers mouth. At the free end, the mouthpiece 2 is thinned out in one direction and widened out in the other, as shown at 3. The mouthpiece is formed with a bore or smoke duct 4 which conforms in shape to the exterior shape of the mouthpiece at the free end. Thus, the smoke duct 4 terminates at the free end in an elongated slot or seat such as shown at 5 in Fig. 3, and preferably but not necessarily of slightly oval-funnel shape.

Referring to Figs. 2, 3, and 4, a cap or plug member is therein illustrated and referred to in its entirety by the reference character 6. This cap member has a closed end or bottom "I to which is joined the side wall structure 8. This side wall structure practically conforms in shape to the interior of the flattened out oval shape of the mouthpiece at 9, and is designed to loosely and removably fit therein in the manner shown in Figs. 2 and 3. Secured to the cap member 6 at ID in any desired or convenient manner is a tube II, one end thereof extending within close proximity to the closed end or bottom I of the cap member, while the other end of the tube extends outwardly sufficiently to be conveniently inserted and frictionally held in the bore or smoke duct 4 of the mouthpiece 2, to prevent accidental separation of the cap member 6 from charging into the secondary chamber through perforations l2. The channels I3 are widened at the outlet ends relative to the inlet ends thereof to restrict the passage of smoke discharged from the secondary chamber and to retard and hinder any flow of saliva or similar oral liquid matter into the interior passages of the mouthpiece. It is obvious that the cap thus acts as a restriction to the smoke duct which prevents the establishment of a free or open draft,

This construction enables the smoke when drawn through the bore or duct 4 to enter the tube II, and pass into the side wall structure 8 of the cap 6, but due to the closed end I is caused to pass through the perforations [2 into the mouthpiece at 9 and from there is then permitted to pass out around the side wall structure 8 into the mouth of the smoker through the depressed portions or channels I3.

In the simplified form illustrated in Fig. 5, most of the material of the portion of the cap 6 containing the perforations I2 is cut away with the exception of the downwardly extending elements I4 which provide means for securing the cap 6 to the tube I I.

In the simplified form illustrated in Fig. 6, the tube I I has been entirely dispensedwith and the downwardly extending elements I4 of the cap Ii are of sufiicient length to enter the bore or smoke duct 4 of the stem 2 to Irictionally and removably hold the cap 6 therein.

In the simplified structures illustrated in Figs.

tremely unpleasant and annoying, and which also provides means for effectually preventing the passage of saliva and moisture from the smokers mouth into the duct or bore, where it might prov mote the formation of disagreeable substances.

The structure is simple in construction and inexpensive to manufacture from suitable material, preferably light metal, by the use of ordinary punches and dies. v I

The foregoing disclosure is to be regarded as descriptive and illustrative only and not as restrictive or limitative of the invention of which obviously embodiments may be constructed including many modifications, without departing from the spirit and scope herein set forth and denoted. in the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: a

In a mouthpiece for a smoking: utensil having a central bore terminating in a flared seat at the outer end thereof, the combination with said mouthpiece of a hollow coniform plug arranged in said seat and communicating with said bore to primarily receive smoke therefrom; said plug being in substantial engagement with said seat in the base portion thereof and radially spaced therefrom in the apex portion thereof to form a circumferential secondary smoke chamber around said apex portion and having sideapertures in a said apex portion to communicate with said secondary chamber, an intake tube connected at one end to said plug in the apex thereof and extending inwardly thereinto beyond said side apertures and connected at the opposite end to said bore, said plug having a plurality of circumferentially spaced exterior longitudinal channels depressed in the base portion thereof and communicating with said secondary chamber to discharge smoke JAMES H.
